Our take

The bottom line

ChartMill and The Fly Pro cover a lot of the same ground (9 shared categories, including screeners, stock comparison, and data visualizations), so for the basics you won't go far wrong with either. ChartMill simply does more: 24 categories to The Fly Pro's 13, including stock ideas, scores, and valuation models. The Fly Pro counters by keeping things simpler.

Questions we keep getting

What's the difference between ChartMill and The Fly Pro?

How much do ChartMill and The Fly Pro cost?

Good news: both ChartMill and The Fly Pro have free plans, so you can run them side by side and only pay if you hit a wall.

Does ChartMill or The Fly Pro have an API?

The Fly Pro has an API for programmatic access and custom integrations. ChartMill doesn't, so you're working through its interface.

Should I choose ChartMill or The Fly Pro?

It depends on what you're after. Pick ChartMill if stock ideas and scores matter to you; go with The Fly Pro if you'd rather have ETF screeners and transcripts. And if you only need the basics both share, let price decide.

Does ChartMill or The Fly Pro have real-time data?

ChartMill exports to CSV. The Fly Pro is stingier about getting data out.

Is ChartMill or The Fly Pro better for day trading?

Which has a better stock screener: ChartMill or The Fly Pro?

Both ChartMill and The Fly Pro include stock screeners, and they differ more in interface than raw power; try both and see which one clicks for you.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
